Interesting that you should mention that, because that is exactly what I am trying to do as well. I have a small 2 wheeled robot (uses modified RC servos for motors), and I am writing a LOGO interpreter on a 16C/F84 so my son can learn a little bit about programming by sending LOGO commands to an autonomous robot. Initially the LOGO commands will be stored in the internal EEPROM, but eventually I will include an IR receiver on the robot that will receive the LOGO program from a PC equipped with an IR transmitter and store the LOGO commands in an external (to the PIC) EEPROM. I will post details when I get it working.

That's how I tested my interpreter before I wrote the serial loader code to put data into the eeprom.
